While that was certainly the case, I see it slightly differently. I think the bigger argument of 2017 was around a network split. Splitting the network is problematic because one or other of the split chains may experience a hash death (without mitigating difficulty adjustment algorithms), or the so-called "famine and feast" minority hash behaviour, experienced on testnet, and disruptive to users Any proposed changes should factor in network splits as a potential risk. Or perhaps through another lens, you could see a network split as an attack, on a par with a 51% attack, in terms of user disruption. It may in fact, be more potent, since we've never had a serious 51% attack, but we have had network splits I do think the conversation here is MUCH better tempered than 2017.
